Can't prevent laptop from sleeping evey night...
Anyone else out there have problems trying to prevent their computer from *ever* going to sleep? I'm running Win7x64 on my ThinkPad T61p, and although I have gone through all settings on the Power Options screen and set the sleep time to never, it still goes to sleep everynight, about 4 hours after last usage.I have installed the Thinkvantage system driver and power management driver, but I am not using the ThinkVantage Power Management app.Eventlog event when the system sleeps is:Log Name: SystemSource: Microsoft-Windows-Kernel-PowerDate: 2/2/2009 3:12:56 AMEvent ID: 42Task Category: (64)Level: InformationKeywords: (4)User: N/AComputer: Lightbulb7Description:The system is entering sleep.Sleep Reason: Application API...but I have no idea who is forcing the api call.Seems like alot of people have problems with their machines not going to sleep...but I didn't see many who couldn't disable sleep mode.KeithRunning Win7x64

I am seeing the same thing on a ThinkPad T61 with 64-bit Win 7 Pro. I still haven't found the source of this though. Some days it doesn't happen at all and on other days it occurs multiple times.
